| cell fractionation | <technique> Strictly this should mean the separation of homogeneous sets from a heterogeneous population of cells (by a method such as flow cytometry). The term is more frequently used to mean subcellular fractionation i.e. The separation of different parts of the cell by differential centrifugation, to give nuclear, mitochondrial, microsomal and soluble fractions. (26 Mar 1998) |
|---|---|
| dose fractionation | Adminstration of the total dose of radiation (radiation dosage) in parts, at timed intervals. (12 Dec 1998) |
| indole-3-ethanol oxidase | <enzyme> Involved in conversion of indole-3-ethanol to indole-3-acetic acid; isolated from seeds of the bean phaseolus vulgaris; not stimulated by nadp or fad; do not confuse with nad- or nadp-dependent indole-3-ethanol oxidases Registry number: EC 1.1.- Synonym: tryptophol oxidase (26 Jun 1999) |
| ethanol | <chemical, drug> Grain alcohol, made from sugar, starch and other carbohydrates by fermentation, has sedative properties (27 Sep 1997) |
| ethanol acyltransferase | <enzyme> Forms ethyl palmitate; responsible in part for the synthesis of fattyl acid ethyl esters; uses ethanol and fatty acyl-CoA as substrates Registry number: EC 2.3.1.- Synonym: acyl coenzyme a-ethanol acyltransferase, acyl CoA-ethanol acyltransferase (26 Jun 1999) |
| fractionation | A term used to describe any method for separating and purifying biological molecules. See: cell fractionation. (18 Nov 1997) |
| paroxysmal cold haemoglobinuria | <haematology> A rare blood disorder caused by antibodies which destroy red blood cells upon exposure to the cold. The antibodies are formed against a specific blood group and are triggered by the cold. The cause is unknown but the disease has been associated with syphilis and some viral infections. Serum haemoglobin and urine haemoglobin are increased during the attacks. The disease is chronic and treatment is difficult. Some cases resolve spontaneously without treatment. Origin: Gr. Ouron = urine (27 Sep 1997) |
| rose cold | Allergic rhinitis occurring in the spring and early summer. (05 Mar 2000) |
| warm-cold haemolysin | Haemolysin which combines with red blood cells at temperatures below 20°C and are eluted at warmer temperatures, e.g., 30 to 37°C. See: Donath-Landsteiner cold autoantibody, haemagglutinating cold autoantibody. (05 Mar 2000) |
| cold | <virology> A slang term that describes a viral upper respiratory infection which results from inflammation of the mucous membranes of the nasal cavity. (27 Sep 1997) |
| cold abscess | An abscess without heat or other usual signs of inflammation. Synonym: tuberculous abscess. (05 Mar 2000) |
| cold agglutination | The agglutination of red blood cells by their own serum (see autoagglutination), or by any other serum when the blood is cooled below body temperature, but most pronounced below 25°C; the phenomenon results from cold agglutinins; may be seen occasionally in the blood of apparently normal persons or as a pathologic finding in patients with primary atypical pneumonia, infectious mononucleosis, and other viral diseases, certain protozoan infections, or lymphoproliferative neoplasms. See: autoagglutination. (05 Mar 2000) |
| cold agglutination test | <investigation> A test for blood antibodies which are present in certain peculiar types of pneumonia (atypical pneumonia, Mycoplasma) (27 Sep 1997) |
| cold agglutinin | An antibody which reacts more efficiently at temperatures below 37°C. (05 Mar 2000) |
| cold agglutinins | <haematology> Antibodies that agglutinate particles with greater activity below 32C. They are IgM antibodies specifically reactive with blood groups I and i in humans and agglutinate red blood cells on cooling, causing Raynaud's phenomenon in vivo. (18 Nov 1997) |
